Drug-Drug Interactions Between Rifapentine and Dolutegravir in HIV/LTBI Co-Infected Individuals

This study will evaluate the potential drug-drug interactions between dolutegravir (DTG) and steady state rifapentine (RPT) when RPT is given with isoniazid (INH) daily for 4 weeks (1HP) as part of treatment for latent TB infection (LTBI) in HIV-1 and LTBI co-infected individuals.

NCT04272242 HIV Infection LTBI
MeSH:Infection HIV Infections

5 Interventions

Name: Dolutegravir (DTG)

Description: Administered orally
Type: Drug
Group Labels: 2

Arm 1: DTG + INH + RPT Arm 2: DTG + INH + RPT

Name: Isoniazid (INH)

Description: Administered orally
Type: Drug
Group Labels: 2

Arm 1: DTG + INH + RPT Arm 2: DTG + INH + RPT

Name: Rifapentine (RPT)

Description: Administered orally
Type: Drug
Group Labels: 3

Arm 1: DTG + INH Arm 1: DTG + INH + RPT Arm 2: DTG + INH + RPT

Name: Antiretroviral Therapy (ART)

Description: Participants will remain on DTG-based ARV treatment with 2 NRTIs (excluding TAF) during the study. NRTIs will not be provided by the study. Arm 1 participants will take non-study supply of DTG for morning doses, and will take study-supplied DTG for evening doses. For Arm 2 participants, DTG will be from non-study ARV supply.
Type: Drug
Group Labels: 2

Arm 1: DTG + INH + RPT Arm 2: DTG + INH + RPT

Name: Pyridoxine (Vitamin B6)

Description: All participants must receive 25 or 50 mg of pyridoxine (vitamin B6) with each dose of INH, based on the current local, national, or international dosing guidelines. Pyridoxine is not provided by the study.
Type: Dietary Supplement
Group Labels: 2

Arm 1: DTG + INH + RPT Arm 2: DTG + INH + RPT


Primary Outcomes

Measure: DTG PK Parameter Maximum Plasma Concentration (Cmax) by visit week and arm

Time: Measured at Days 0 and 28

Measure: DTG PK Parameter Area Under the Curve (AUC0-12 for BID & AUC0-24 for QD dosing) by visit week and arm

Time: Measured at Days 0 and 28

Measure: DTG PK Parameter Minimum Plasma Concentration (Cmin) by visit week and arm

Time: Measured at Days 0 and 28

Secondary Outcomes

Description: Graded according to the Division of AIDS Table for Grading the Severity of Adult and Pediatric Adverse Events (DAIDS AE Grading Table), corrected Version 2.1, July 2017

Measure: Proportion of participants with all adverse events meeting the reporting criteria in the study protocol during administration of DTG with 1HP, by arm

Time: Measured through Week 4

Measure: Proportion of participants who discontinue study or study drugs during DTG and 1HP dosing, by arm

Time: Measured through Week 4

Measure: Proportion of participants with HIV-1 RNA levels >50 copies/mL

Time: Measured at Days 28 and 42

Purpose: Treatment

Allocation: Non-Randomized
